Abstract

The utility model relates to a steam-water dual-purpose energy saving boiler. A boiler chamber communicated with a smoke channel is arranged in an existing boiler body. The lower part of a hanging chamber arranged in the boiler chamber is a concave cavity on the basis that the bottom of a fire grate is provided with a primary air device and a second and a third air nozzles which are contained by an air pipe are arranged on the peripheral wall of the boiler chamber. Layers of air holes are arranged in the peripheral wall of the boiler chamber, and a sealing head on the boiler chamber near the air pipe is provided with a quartic air nozzle. The heating area of the concave cavity of the hanging chamber is enlarged, and a combustion space is provided for coal with high heat value. The quartic air nozzle can generate oxygen enriched air to perform the double functions of combustion supporting and dust removing. The utility model has the advantages of thorough combustion, wide adaptation of coal, high heat efficiency, energy saving, etc.

Description

The steam-water dual-purpose power economized boiler

The utility model belongs to the dual purpose steam water boiler field.

Existing dual purpose steam water boiler hang courage bottom heating surface be circular flat and with coal-fired layer close together, be only limited in the burning, the low heat value fire coal; Several elbow shape convection current radiation resistance dirt heating tubes that are provided with in hanging courage under the situation of pipeline pyrotechnics Channel Group, have the effect that increases heating surface, but because coal-fired dust and crock have just lost due effect after making pipe blocking.

The purpose of this utility model is to provide that a kind of heating surface area is big, sufficient combustion, coal is scalable, the thermal efficiency is high, save the steam-water dual-purpose power economized boiler of the energy.

The purpose of this utility model is realized by following technical scheme: a kind of steam-water dual-purpose power economized boiler, comprise body of heater (9), flue (15) is set in body of heater (9), the neck of flue (15) is communicated with flue (12), flue (15) also is communicated with flue (12) by flue convection tube (10), in flue (15), be provided with and hang courage (8), hang courage (8) on, the lower end be respectively equipped with make hang that cavity is communicated with between courage (8) inner chamber and body of heater (9) and the flue (15) on, following circulation pipe (13) and (5), secondary air box (11) and fire grate (16) are set in the bottom of flue (15), in the bottom of body of heater (9) wind apparatus (1) is set, a wind apparatus (1) is communicated with secondary air channel (2), secondary air channel (2) is communicated with secondary air box (11), airduct (3) is set on the perisporium of flue (15), airduct (3) and secondary air box (11), secondary tuyere (4) on flue (15) perisporium and tertiary air mouth (6) are communicated with, its special character is: be provided with re-entrant cavity (14) in the bottom of hanging courage (8), be provided with the windy hole of multilayer (17) on the perisporium of flue (15), also be provided with four tuyeres (7) that airduct (3) is communicated with.

Carbonated drink two power economized boilers of the present utility model are compared with existing dual purpose steam water boiler, because the courage that hangs of the present utility model is provided with the re-entrant cavity structure, have increased heating surface area, and the space of burning is provided to high combustion value coal again; Also because on existing one, two, three upright basis of changeing the wind direction structure, again hang increased on the courage Parallel airflow to the windy hole of multilayer and four tuyere structures, form the oxygen-enriched air film, unburnt charcoal can be fully burned.Have advantages such as coal is scalable, the thermal efficiency is high, the saving energy.

The utility model is described in further detail to utilize an embodiment shown in the drawings below.

Accompanying drawing 1 is a structure cross-sectional schematic of the present utility model.

With reference to Fig. 1, a wind apparatus (1) is blown into furnace bottom with wind, makes the coal on the fire grate (16) combustion-supporting.Meanwhile wind enters secondary air box (11), enters in the airduct (3) then by secondary air channel (2) again, airduct (3) is included in last two, three, four tuyeres (4), (6), (7), the windy hole of multilayer (17) that is provided with of flue (15) and is welded on the perisporium of flue (15), and the cold wind in airduct (3) is heated.Hot blast is by secondary tuyere (4), the windy hole of multilayer (17), tertiary air mouth (6) enters in the burner hearth, interior imflammable gas of stove and flue gas rotation are risen cause the chance of imflammable gas second-time burning, hot blast in the airduct (3) continues to rise to four tuyeres (7) and locates, hot blast enters in the burner hearth, four wind are that Parallel airflow is to structure, hanging courage (8) bottom formation oxygen-enriched air film, under the effect of oxygen-enriched air film, the top that makes unburnt imflammable gas be blended in the combustion chamber forms gas-fired, make fully burning under the high temperature of flammable carbon in stove of combustion chamber, produces a large amount of heats and pass to the water that hangs between courage (8) interior and body of heater (9) and the flue (15) fast.Because the bottom of hanging courage (8) is provided with re-entrant cavity (14), has the heating surface area of increase, stop unburnt flammable charcoal to return burning and provide a clean-burning space for high combustion value coal.The setting of upper and lower circulation pipe (13) and (5) makes and hangs courage (8) inner chamber and be communicated with cavity between body of heater (9) and the flue (15), and heat is transmitted rapidly, and the heating that utilizes boiler water is arranged.The neck of flue (15) is communicated with flue (12), and flue (15) also is communicated with flue (12) by flue convection tube (10), and a small amount of cavity of flue gas in flue (15) flows into flue (12) and flow into flue (12) by flue convection tube (10) and discharge.
